Still as an older guy i find i need to read small text at the most inopportune times so i like having a small magnifier on my key chain which i always carry with me

This comes from china and was supposed to take up to 28 days to get to me in connecticut but i received it in about a week so that was a surprise

Its thick and the magnified image does look quite a bit darker when using it

I can recommend this unit for its price and usability and protective features
